EYELETING-PUNCH.

SPECIFICATION forming part of Letters Patent No. 279,@93, dated June 12, 1883,

' Application filed January 12, 1859. (No model.)

To all whom it may concern;

Be it known that I, ,CHARLES MORRI'LL, of New York city, New York, have invented certain new and useful Improvements in Eyeleting-Punches, of which the following is a specification.

My invention relates more particularly to that class of hand-tools adapted for cutting or punching small holes in leather or other materials for the insertion of eyelets, laces, or other devices; and-it consists in the special construction, arrangement, and combination of parts hereinafter described and claimed.

-v In the drawings annexed, Figure l presents a side elevation of my improved tool, and FiO. 2a front elevation thereof. Fig. 3gives avertical section of the punch and die removed, and Fig. 4 shows a plan view of the die removed.

In Figs. l and 2, a indicates the main jaw or lever-handle of the tool, andb the minor or movable lever, which is pivoted to the former by the pin o. The main jaw has its forward end bent laterally into the form of a U, forming a crotch or recess, into which the leather or material to be punched may be inserted. Through the outer branch of this U-shaped bend, vwhich `forms the tip of the main i aw, is bored a tapped hole or socket, into which is screwed a tubular die, c, whose inner end protrudes alittle beyond the inner face of the j aw, thus presenting` an abutting-snriace, against which the leather or material to be punched may rest, as indicated by dotted lines in Fig.

l. The inner or abutting` end of this die may be flat, or it may be beveled to an obtuse edge from the edge of the bore, as shown in Figs. l and 3, While its upper and outer end is preferably formed with a stop-shoulder, d, and with a square socket, as seen in Figs. 4 and 3, for the insertion of a wrench, by which the die can be easily removed or inserted by screwing it in or out, as will be understood.

Through the middle or body of the main jaw, a., is formed a longitudinal bore or socket, in

\ which is nicely fitted a reciprocating rod or plunger, lz', which works in direct or central line with the fixed die, as shown in Figs. l and 2. On the upper end of this plunger-rod'is Xed the solid punch e, whose point and main portion is a snug iit for the bore of the die, as shown bestV in Fig. 3, and is adapted to enter the die when forced forward, as will be understood. The base of this punch is formed with a tapering shank, g, which ts snugly into a corresponding tapering socket in the top of the plunger l1, as seen best in Fig. 3, and the punch has also a broad seating shoulder or rim, j', which seats upon the top of the plunger, there` by supporting the die firmly on the plunger and connecting it therewith by a simple frictional fit, which admits of the punch being readily removed and replaced, as will be understood.

To facilitate the removal or replacement of the punch, the shoulder is made iiatsided or hexagonal, so that a small wrench may be placed over the same Vto obtain a twisting motion upon the punch, which renders i-ts insertion or removal easy, as will be readily seen.

The lower` or i nner en d of the plunger 7i rests against a short camarm7 b', o n the minor or pivoted lever-handle b, ,so that when the handles of the tool are grasped and the pivoted handle b moved toward the main handle a the cam-arm b on the handle I) will move the plunger 71, forward with great leverage and force the punch toward and into the die, so as to forcibly yet easily punch or cut a hole in the material placed between the two equal to the size of the punch, the removed piece or core being forced by the advancing punch i11- to and throughthe bore of the die, thus rendering the tool self-clearing at each action.

When the pressure on the handles of the tool is relaxed, a spring, t, causes the plunger 71` and punch e to retreat from the die and retire back to their retracted position, as shown in Figs. 1 and 2,which motion, of course, also swings outfthe pivoted lever-handle b into its distended position, as seen in Fio. l. The spring 'i' is preferably a spiral, as shown, encircling the plunger 71. in a recess or cavity, if, formed in the front of the main jaw a, and eX- tending through the middle of the bore or socket in which the plunger slides. One end of the spring bears against the upper end of the recess, while the lower end bears upon a washer, Z, surrounding the plunger and resting against a stoppin, m, driven into the plu11- ger, which pin seats against the lower end of the recess when the plunger is retracted, as will be understood. This pin m projects from the plunger far enough to strike the side of IOO the recess 7c, and thus prevent the plunger turning in its socket, so that the punch c may be readily inserted in or removed from the plunger by a rotating or partly rotating motion, which could not be easily done if the plunger were free to revolve, as will be readily understood. It will therefore be now understood by reference to l, 2, and 3 that when the leather or material to be punched or perforated is placed between the die and punch, and when the handles of the tool are forced together, the punch will be forced against and into the material on one side, while the material will be pressed against the die on the other side,and that the sharp edges of the die will cut for a slight depth into one side of the material,whilc the punch will cut into the opposite side and force its way through the substance partlyby a cutting and partly by a punching action, therebyremoving a core ofthe material equal in size itself, which core becomes finally detached as the die passes through the material, while the core is then forced into and finally ejected from the-bore of the die as the punch enters the same, as will be understood. It will therefore be appreciated that not only will. this tool p erforate the material in an easy, accurate manner and clear itself of the cores as fast as cut, as before described, but in addition to this the edges of the hole thus formed will be cut clean and sharp on each side of the material, and also slightly depressed or countersunk on each side, thus rendering the work neat and the holes better adapted to receive the eyelet or other inserted device. lt will also be seen that, as Ythe tool is self-clearing at cach action, the work can be performed much better, easier, and faster, and the work will be rendered .i more neat and perfect, for the penetration of the punch into the material is not retarded by clogged cores, and no stoppages are required to clear out the same, as frequently occurs with the present tools. Moreover, as the punch is solid and formed with a strong countersunk cutting-tip, it possesses a construction which is much cheaper, simpler, and far more strong and durable than the usual h ollow punch. lt may be also noted that, as the socket for the die and the punch-plunger are formed through the main jaw of the tool in direct line with each other, hence these sockets may be bored by the same tool,which insures perfect alignment, and as the die and punch and plunger are all turned or circular the construction of the tool. may be made very accurate, yet very cheap and simple. It will be also noted that the simple removable connection of the die and punch with the tool, as before described, renders it very simple to change one die and punch for those of another size or shape, thereby giving the tool great scope and convenience, for it is of course my intention to accompany the tool with a graduated set of rdies and punches adapted for forming holes of various shapes and sizes, yet all adapted to 'fit the sockets of the tool, as will bc understood, thereby presenting an eyeleting or punching tool which possesses many marked advantages over those heretofore 4in use.

Instead of having the punch to socket on the tip of the plunger by a simple frictional fit, it may be` preferable to have the shank of the punch threaded to screw into a threaded socket on the plunger in a manner similar to the die.

I do not wish to be understood as claiming, broadly, a hollow die or abutment, in combination with a solid punch to enter the same. Neither do I wish to infer novelty in the use of removable or changeablel punchesor abutmcnts in eyeleting-tools, but i Vhat I claim as my invention is as follows:

l. In an eycleting-machine, the combination of the stock a., having the longitudinal socket for the punch and a spring-chamber, with the handle b,pivoted directly to the stock c at a point at one side of the plane of the motion of the punch, and having a cam formed on the end of the handle for operating said punch, substantially as described.

2. The combination, with the main stock or handle c, having a lateral bend at its tip,with a sliding plunger, 71, adapted to move in said stock at right' angles to said bend, a punch affixed on the end of said plunger, and a die or abutment fixed on the tip of said bend coincident therewith, with the movable leverhandle b, having cam-arms b bearing on said plunger, and a spring to retract said plunger and handle, substantially as herein shown and described.

3. The stock a, having punch-socket and spring-chamber, as shown, andhaving also the bent portion to receive the removable interchangeable die, and the pivoting-lug extending beyond the plane ofthe 1n otion ofthe punch, combined with the handle b, ,pivoted directly to the stock a, and having cam b, which is adapted to lie when in operation about midway between the two handles, and to give a direct stroke to the punch, the said punch, spring fi, and the die c, as and for the purposes set forth.
